As seen in the previous tutorials, operations such as FFT, MUX/DEMUX, encoding, modulation,​... are processed via GNU Radio blocks all over the flow graph. In other words, the transmitted waveform is "soft shaped"​ by GNU Radio. ​

The goal of this tutorial is to transmit IEEE 802.15.4 packets with a "​Hard"​ transmitter,​ it means that the waveform is generated by the PicoSDR, by taking a ''​.hex''​ file as an input and processing it through an FPGA design, using [[http://​whatis.techtarget.com/​definition/​IP-core-intellectual-property-core|IP cores]] written in hardware description language (HDL) code. ​

In this tutorial, we will see how to transmit and receive IEEE 802.15.4 packets using a .hex file as an input and a [[custom Bitstream]] of a IEEE 802.15.4 PHY Layer Transmitter targeting the Xilinx FPGA [[https://​www.google.fr/​url?​sa=t&​rct=j&​q=&​esrc=s&​source=web&​cd=2&​ved=0ahUKEwi_197x2-bXAhUHrRQKHXmRCWQQFggxMAE&​url=https%3A%2F%2Fwww.xilinx.com%2Fsupport%2Fdocumentation%2Fdata_sheets%2Fds150.pdf&​usg=AOvVaw0Z12Npy0fD0V2OybYMhTkH|Virtex6]] of the [[https://​www.nutaq.com/​products/​picosdr|PicoSDR]] ​
